Study on Lateral Dynamic Response of Pile Foundation in Liquefiable Soil by Using FBG Method
The study on lateral dynamic response of pile foundation in liquefiable soil is a significant part about seismic damage.In this paper,a new data acquisition system of FBG and calculation methods is used in the small shaking table test.The results show that FBG method used in this test is proved to be efficient and acceptable in both time characteristics and precision characteristics,it may be widely applied in the future doubtlessly.Whats more,the characteristics ofp-y curves in different peak accelerations are discussed.And varying of maximum stress and displacement by corresponding acceleration is discussed.A contrast about p-y curve between dry sand and saturate sand is related,which provides a new direction in research about p-y curve.
